Serving trays serve as message boards with some chalkboard paint(I used Crayola brand), wire, 2 rivets, and 4 clear 3/8" vinyl bumpers for the back. When adding the rivets for the hanger, I also added a black washer to the front on one side so that I could add ribbon & chalk.
To personalize you can either paint or decal the edge. These make great gifts.
Serving trays can be purchased for change at thrift stores and yard sales. Certain steps of this project can be done with children as long as they are supervised.
